Sometime during the third millennium, the majority of earth’s population perished in a storm of nuclear detonations, kinetic impacts, bio-weapon plagues and all consuming nano-swarms. An apocalyptic interstellar war, colloquially known as the Untergang, ravaged all worlds of man. Civilization collapsed and humanity on earth was brought to the brink of extinction. But humankind managed to survive.
Centuries went by and a severely changed earth emerged, marked by the disastrous cocktail of catastrophes unleashed on the hapless planet. The ancestors of the survivors formed a variety of primitive societies, continuously warring for the scant resources available. The manifold causes and rapid chain of events of the Untergang, along with most history before it, fell into oblivion.
